The AS12 was larger than the SS11 with a 165lb HE warhead which was fitted for annual firings. (although not all I seem to remember)
The AS12 range was 7500 yds (lots of copper wire!) and the SS11 range was about 3500-4000 yds?. Anyway, TOF AS12 32 seconds (ambient temperature dependant) and the SS11 about 18 seconds.
As sloppy link says, it was a bugger to control at long range because of the time it took for control inputs to travel down the wire to the control surfaces.
The other great 'feature' with these things was the nasty habit of the redundant wire getting caught up in the MRH after missile impact. The way to stop that was for the pilot to pull up and right after missile impact and for the aimer to then cut the wires. Not before. Doh!
